If dark matter is creating positrons in the CMZ, those particles will eventually slow down and eventually annihilate with electrons in the environment, producing gamma-rays at exactly 511keV energy.

Abstract: In real-life operation, electronic devices are exposed at the same time to different sources of ionizing radiation. In this paper, we evaluate the impact of ...
